8 EA L- LO C K SPECIFICATION forming part of Letters Patent No. 607,512,dated July 19, 1898. Application filed June 2, 1897. Serial No. 639,191.(No model.)

To all whom it may concern.-

Be it known that we, OTTO B. KIRKPATRICK and GEORGE L. BANKS, citizensof the United States, residing at Colorado Springs, in the county of ElPaso and State of Colorado, have invented certain new and usefulImprovements in Seal-Locks; and we do declare the following to be afull, clear, and exact description of the invention, such as will enableoth ers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

This invention relates to seal-locks; and it relates particularly tothat class of these locks which are designed for use upon doors, such ascar-doors, and whereby the fact of the door being opened after beinglocked will be at once apparent upon inspection.

The object of the invention is to provide a seal-lock of the kinddescribed which shall be of simple and cheap construction, sure inoperation, and by which a door may be fastened in such manner as torender it necessary to destroya part of the look before the door can beopened, thereby insuring the indication of the fact of opening.

Further, the object of the invention is to provide a seal-lock adaptedfor use on sliding doors, such as car-doors, the lock having combinedtherewith and forming part thereof an easily-destructible portion whichis so formed as to engage a catch upon the door and retain the sameuntil the destru'ctible portion is With these objects in view theinvention consists in the construction and relative arran gement andoperation of parts, all of which will be found hereinafter fully andclearly set forth.

The invention is illustrated in the accompanying drawings, in which-Figure 1 is a side elevation of our improved lock, the same being shownon a car and in a locked position. Fig.2.is aperspective view of themain body of the lock. Fig. 3 is a perspective view showing the underface of the fragile or destructible portion bearing the catch; and Fig.4 is a side elevation of the hasp, which is adapted to .be attached to adoor.

In the drawings, A represents the main body portion of the lock, whichis provided with projections a a, having openings therein for thereception of screws or the like by which the body is attached to theside of a car or other structure adjacent to a door. The main bodyportion is formed with two intersecting grooves arranged at right anglesto each other and in different planes. The groove a is arranged in therear of the body, and it is adapted for the reception of the hasp C, tobe described hereinafter.

The transverse groove A is arranged forward of the groove a, and thislast-mentioned groove has overhanging edges a a on each side of thegroove, the overhanging edges being integral with the body A.

B represents a plate which is designed to be introduced into the grooveor way A and to that end has its edges beveled to accurately fit beneaththe overhanging edges d The portion B is constructed of some suitablematerial which will Withstand the ordinary jar imposed upon it when thelock is applied to a railway-car and which at the same time may bequickly and easily destroyed by a blow from a hammer or by cutting witha sharp instrument, as desired. To this end the portion B may be ofglass, earthenware, papier mach, soft wood, or other suitable substance;

The under side of the portion B is provided with a transverse groove 1),and arranged in this groove and projecting downward therefrom is aspring lip or catch 1), which may be formed integral with the portion Bor may be of different material and attached to it by suitable means toretain it in the proper position to perform its function.

0 represents a hasp,.which is provided at one end with an opening 0,permitting its attachment to a door, such as a sliding door of arailway-car, and at the other end is provided with a hook c. The haspis'also' provided a short distance from its free end with a raisedportion 0 adapted to abut against the face of the body A, which isadjacent to the door to which the hasp is attached.

In the use of the device the parts are suitably arranged in position,the body A being permanently attached to a structure, such as arailway-car, at the edge of the door-jamb, and the hasp is secured to asliding doorby a staple or in any other suitable manner. The fragile ordestructible portion 13 of the lock is slid into the groove A to bringthe groove 1) in the portion B to register with the groove a in the bodyA. When the parts are in this position, the hasp is introduced into theopening formed by the grooves a and the grooves 1) until the hook c isengaged by the spring portion b, the inward movement of the hasp beinglimited by the projection 0 When the parts are in this position, it willbe seen that removal of the hasp from the lock is prevented, the springengaging the hook preventing the withdrawal of the hasp and theengagement of the portion B with the overhanging edges a and theentrance of the hasp into the groove 1) preventing the withdrawal orremoval of the fragile or destructible portion B. The only way in whichthe hasp can be released is by breaking, cutting away, or in some othermanner removing or destroying the portion B.

The destructible portion, the removal of which is necessary to releasethe hasp, may

be provided with any suitable marks of identification whereby itsgenuineness may be determined.

Having thus described our invention, What we claim as new, and desire tosecure byLetters Patent, is-- A seal-lock comprising a body having twogrooves arranged therein at right angles to each other and in differentplanes, one groove being adapted for the reception of a hasp or thelike, and the other being adapted for the reception of a destructiblebody, the destructible body being provided on its under face with agroove corresponding to the first groove in the main body and with aspring projection, and a hasp having a hook at its end and adapted toenter the groove in the main body and also that in thedestructibleportion, and to be engaged by the spring projection, substantially asdescribed.

In testimony whereof we aflix our signatures in presence of twowitnesses.
